Colorectal cancer disease profile and treatment patterns at an urban tertiary hospital in Rwanda.

Background: The incidence of colorectal cancer (CRC) in sub-Saharan Africa (SSA) is rising, due to improving cancer registration efforts on one hand and an increasing westernisation of diets and lifestyle on the other as well as increasing rates of comorbidities. Methods: We present data for the clinical characteristics, pathology, treatments received, and survival outcomes of patients diagnosed with CRC at King Faisal Hospital (KFH) between January 2019 and May 2023. KFH is an urban tertiary hospital in Rwanda that provides chemotherapy and surgery to cancer patients. The data were extracted from electronic medical records, imaging and histopathology reports from the patient's time of diagnosis. We plotted Kaplan-Meier estimation of survival, defined as the time from presentation to death, within the study period (2019-2023). Results: Seventy-four patients diagnosed with CRC with complete information were identified in the KFH oncology records. The mean age at diagnosis was 54.6 years, with ages ranging between 22 and 81 years. At diagnosis, 24 (32.4%) patients were less than 50 years old and 29 (39.2%) were females. The rectum (36.5%) was the most common tumour location, and 58.1 tumours were left-sided. Most patients presented with Stage III (41.9%) or IV (35.1%) disease. Adenocarcinoma was the most common histological type (98.6%) including adenocarcinoma not otherwise specified (NOS) (86.5%), mucinous adenocarcinoma (10.8%), signet ring cell carcinoma (1.4%) and followed by squamous cell carcinoma (1.4%). In terms of treatment, 19 (25.7%) patients received only chemotherapy, 43 (58.1%) patients received neo-adjuvant or adjuvant chemotherapy, 9 (12.2%) of patients received both neo-adjuvant and adjuvant chemotherapy, 49 patients (66.2%) underwent surgery and 17 (23%) patients also received radiation. At the end of the follow up period, 63 (85.1%) patients remained in surveillance, 10 (13.5%) patients died, and 1 (1.3%) patient was lost to follow up. Mean overall survival was 45.5 (SD ± 2.0) months. Conclusion: CRC patients presented at an advanced stage and required complex treatment regimens at KFH. Further epidemiologic and molecular research is needed to characterise CRC incidence and presentation at a national level in Rwanda as increasing westernisation continues to change the face of CRC in urban areas of SSA.

Financial Toxicity: Unveiling the Burden of Cancer Care on Patients in Rwanda.

INTRODUCTION: Cancer is a major public health problem in Rwanda and other low- and middle-income countries (LMICs). While there have been some improvements in access to cancer treatment, the cost of care has increased, leading to financial toxicity and treatment barriers for many patients. This study explores the financial toxicity of cancer care in Rwanda. METHODS: This prospective cross-sectional study was conducted at 3 referral hospitals in Rwanda, which deliver most of the country's cancer care. Data were collected over 6 months from June 1 to December 1, 2022 by trained research assistants (RAs) using a modified validated data collection tool. RAs interviewed consecutive eligible patients with breast cancer, cervical cancer, colorectal cancer, Hodgkin's and non-Hodgkin's lymphoma who were on active systemic therapy. The study aimed to identify sources of financial burden. Data were analyzed using descriptive statistics. RESULTS: 239 patients were included; 75% (n = 180/239) were female and mean age was 51 years. Breast, cervix, and colorectal cancers were the most common diagnoses (42%, 100/239; 24%, 58/239; and 24%, 57/239, respectively) and 54% (n = 129/239) were diagnosed with advanced stage (stages III-IV). Financial burden was high; 44% (n = 106/239) of respondents sold property, 29% (n = 70/239) asked for charity from public, family, or friends, and 16% (n = 37/239) took loans with interest to fund cancer treatment. CONCLUSION: Despite health insurance which covers many elements of cancer care, a substantial proportion of patients on anti-cancer treatment in Rwanda experience major financial toxicity. Novel health financing solutions are needed to ensure accessible and affordable cancer care.

Germline Testing Around the Globe: Challenges in Different Practice Settings.

Cancer is an increasing global public health burden. Lately, more emphasis has emerged on the importance of heredity in cancer, mostly driven by the introduction of germline genetic variants-directed therapeutics. It is true that 40% of cancer risk is attributed to modifiable environmental and lifestyle factors; still, 16% of cancers could be heritable, accounting for 2.9 of the 18.1 million cases diagnosed worldwide. At least two third of those will be diagnosed in countries with limited resources-low- and middle-income countries, especially where high rates of consanguine marriage and early age at diagnosis are already prevalent. Both are hallmarks of hereditary cancer. This creates a new opportunity for prevention, early detection, and recently therapeutic intervention. However, this opportunity is challenged by many obstacles along the path to addressing germline testing in patients with cancer in the clinic worldwide. Global collaboration and expertise exchange are important to bridge the knowledge gap and facilitate practical implementation. Adapting existing guidelines and prioritization according to local resources are essential to address the unique needs and overcome the unique barriers of each society.

Multidisciplinary approach to cancer care in Rwanda: the role of tumour board meetings.

Introduction: Cancer treatment is complex and necessitates a multidisciplinary approach. Tumour Board Meetings (TBMs) provide a multidisciplinary platform for health care providers to communicate about treatment plans for patients. TBMs improve patient care, treatment outcomes and, ultimately, patient satisfaction by facilitating information exchange and regular communication among all parties involved in a patient's treatment. This study describes the current status of case conference meetings in Rwanda including their structure, process and outcomes. Methods: The study included four hospitals providing cancer care in Rwanda. Data gathered included patients' diagnosis, number of attendance and pre-TBM treatment plan, as well as changes made during TBMs, including diagnostic and management plan changes. Results: From 128 meetings that took place at the time of the study, Rwanda Military Hospital hosted 45 (35%) meetings, King Faisal Hospital had 32 (25%), Butare University Teaching Hospital (CHUB) had 32 (25%) and Kigali University Teaching Hospital (CHUK) had 19 (15%). In all hospitals, General Surgery 69 (29%) was the leading speciality in presenting cases. The top three most presented disease site were head and neck 58 (24%), gastrointestinal 28 (16%) and cervix 28 (12%). Most (85% (202/239)) presented cases sought inputs from TBMs on management plan. On average, two oncologists, two general surgeons, one pathologist and one radiologist attended each meeting. Conclusion: TBMs in Rwanda are increasingly getting recognised by clinicians. To influence the quality of cancer care provided to Rwandans, it is crucial to build on this enthusiasm and enhance TBMs conduct and efficiency.

Pharmaceutical industry relationships with oncologists in sub-Saharan Africa.

Health-care systems in sub-Saharan Africa are considered to be new markets for pharmaceutical companies. This perception is particularly relevant within oncology, as the pharmaceutical industry has changed strategic priorities in the past 10 years to focus on cancer. Since the 1930s, pharmaceutical companies have used advertisements, sample drugs, gifts, paid speaking engagements, advisory boards, and trips to conferences to influence clinical practice and policy. A large amount of literature describes the commonness of these practices and their effects on the behaviour of doctors. However, these data come almost exclusively from high-income countries. Industry-doctor relationships are increasingly common in sub-Saharan Africa and other low-income and middle-income countries. Although there are undoubtedly risks of industry engagement in low-income and middle-income countries, many programmes with educational, research, and clinical value would not occur in these countries without industry support. Thus, what is known about these relationships in high-income countries will not necessarily apply in low-income and middle-income countries. There is a need for widespread discussion about industry-oncologist interactions across the African continent and context-specific data to understand the potential risks and benefits of these relationships.

Geographic Accessibility of Radiation Therapy Facilities in Sub-Saharan Africa.

PURPOSE: Access to radiation therapy in Sub-Saharan Africa (SSA) remains unacceptably low. Prior studies have focused on how many radiation therapy machines a country has but have not accounted for geographic accessibility, which is a known barrier to radiation therapy compliance. In this study, we describe accessibility measured as travel time by road to radiation therapy in SSA. METHODS AND MATERIALS: This study used geographic information systems modeling techniques. A list of radiation therapy facilities was obtained from the Directory of Radiotherapy Centres. We obtained a 1 km2 surface of travel times using a least-cost-path algorithm implemented in Google Earth Engine (Google, Mountain View, CA). AccessMod 5 (World Health Organization, Geneva, Switzerland) was used to compute the percentage of each country's population with access to a radiation therapy facility within prespecified one-way travel time intervals. We then ranked countries using 3 measures of access: 2-hour geographic access, units per capita, and units per cancer case. RESULTS: Only 24.4% of the population of SSA can access a radiation therapy facility within 2 hours of travel by road; access was 14.6% and 42.5% within 1 and 4 hours, respectively. More than 80% of Rwandans and South Africans were within 2 hours of radiation therapy, the highest in the region. Although countries with more radiation therapy units per capita tended to have higher 2-hour access, there was notable discordance between the 2 measures. Mauritania, Zambia, Sudan, and Namibia were among the top 10 countries ranked by machines per capita, but none ranked in the top 10 by 2-hour geographic access. There was similar discordance between 2-hour access and radiation therapy units per cancer case; Rwanda, Nigeria, Senegal, and Cote d'Ivoire ranked in the top 10 for the former but ranked worse using units per cancer case. CONCLUSIONS: Prior measures of radiation therapy access provide an incomplete picture. Geographic location of radiation therapy centers is a crucial component of access that should be considered for future planning in SSA.

Assessing the utilization of cancer medicines in Rwanda: an analysis of treatment patterns.

Introduction: Cancer is a growing public health concern in Africa, especially in low- and middle-income countries (LMICs) like Rwanda. Increased cancer incidences translate into increased utilisation of cancer medicine. Access to affordable cancer medicines in Rwanda is a pressing issue as the National Health Insurance plan does not provide coverage for cancer medicines. In this study, we investigated the utilisation patterns of cancer medicines in Rwanda. Methods: This retrospective cross-sectional study was conducted at all referral hospitals (n = 3) capable of delivering chemotherapy in Rwanda. The data collection was over a period of 6 months, during which a team of trained research assistants reviewed a convenience sample of selected patient charts. Both paper charts and electronic medical records were used to collect patients' data, including cancer type, stage, treatment setting, type of drugs or regimen used and completed cycles. Data were analysed using descriptive statistics. Results: A total of 630 patients received chemotherapy during the study period and were included. Seventy-seven percent (n = 486) were female and mean age was 51 (SD ± 13). Among all patients receiving chemotherapy, 43% (n = 270) had breast cancer, 22% (n = 140) had cervical cancer and 19% (n = 121) had colorectal cancer. The majority of patients (71%) had a community-based insurance. Butaro Cancer Centre treated the most patients (48%, n = 303). Thirty-six percent (221/630) had stage III cancer. The most common regimens within the cohort were adriamycin, cyclophosphamide and taxane, capecitabine and oxaliplatin (CAPOX), paclitaxel + carboplatin and a single agent cisplatin given concurrently with radiotherapy. The proportion of chemotherapy that was given in the curative and palliative setting was 72% and 28% respectively. Conclusion: Access to affordable cancer medicines remains a challenge in Rwanda. The study's findings provide valuable information on the utilisation patterns of cancer medicines in Rwanda, which can be used to guide policy decisions and improve cancer care in the country.

Breast, Ovarian, Uterine, Vaginal, and Vulvar Cancer Care in Low- and Middle-Income Countries: Prevalence, Screening, Treatment, Palliative Care, and Human Resources Training.

Breast, ovarian, uterine, vaginal, and vulvar cancers pose a significant risk to women's lives in low- and middle-income countries due to increasing incidence and presentation with advanced stage disease. There are challenges to screening and early detection and limitations in access to treatment and palliative care, and the current global health care workforce is insufficient. However, there is promise in development of telehealth strategies, task shifting, and increasing number of physician training programs to help address currently unmet needs.

Toward Equitable Access to Tertiary Cancer Care in Rwanda: A Geospatial Analysis.

PURPOSE: Geographic access to care is an important measure of health equity. In this study, we describe geographic access to cancer care centers (CCCs) in Rwanda with the current facilities providing care and examine how access could change with expanded care infrastructure. METHODS: Health facilities included are public hospitals administered by the Rwanda Ministry of Health. The WorldPop Project was used to estimate population distribution, and OpenStreetMap was used to determine travel routes. On the basis of geolocations of the facilities, AccessMod 5 was used to estimate the percentage of the population that live within 1 hour, 2 hours, and 4 hours of CCCs under the current (two facilities) and expanded care (seven facilities) scenarios. Variations in access by region, poverty, and level of urbanization were described. RESULTS: Currently, 13%, 41%, and 85% of Rwandans can access CCCs within one, two, and 4 hours of travel, respectively. With expansion of CCCs to seven facilities, access increases to 37%, 84%, and 99%, respectively. There is a substantial variation in current geographic access by province, with 1-hour access in Kigali at 98%, whereas access in the Western Province is 0%; care expansion could increase 2-hour access in the Western Province from 1% to 71%. Variation in access is also seen across the level of urbanization, with current 1-hour access in urban versus rural areas of 45% and 8%, respectively. Expanded care results in improvement of 1-hour access to 67% and 33%, respectively. Similar trends were also noted across poverty levels. CONCLUSION: Geographical access to CCCs varies substantially by province, level of urbanization, and poverty. These disparities can be alleviated by strategic care expansion to other tertiary care facilities across Rwanda.

Trends of Molecular Testing for Lung Cancer at the King Faisal Hospital, Kigali: Therapeutic and Survival Implications.

Introduction: Lung cancer is the leading cause of cancer mortality worldwide, both in high and low resource settings. Knowledge has been generated elsewhere regarding molecular subtyping and subsequent targeted therapy development, contributing substantially to patient survival. Little is known on the data around lung cancer and its treatment outcomes in Sub-Saharan Africa. This study describes the experience in lung cancer diagnosis, molecular and biomarker testing, and treatment for advanced cases in a single institution in East Africa, between the years 2019 and 2021. Methods: This was a retrospective observational study evaluating patients with metastatic (stage IV) lung cancer. Data on patient demographics, histologic diagnosis, molecular and biomarker testing, and treatment details and outcomes were collected. Molecular test results were reported as positive if there were biomarkers identified (e.g., EGFR, ALK, programmed death-ligand 1), and patients who had negative test results were reported as negative for biomarkers. Results: A total of 14 patients were diagnosed with having stage IV disease, and all were proposed to undergo molecular testing. For 12 (86%) patients who were able to have molecular testing done, EGFR and programmed death-ligand 1 were the most common with 66.7% (N = 8) of tissues with either finding. For all 14 patients, treatment changes were made for eight patients (57.1%) after being primarily placed on a combination of paclitaxel and carboplatin for an average of six cycles. Changing treatment significantly improved the 2-year overall survival (85% versus 25%, p = 0.0006). Conclusions: Despite being the number one cause of mortality, gains are being made in poor-resource settings to improve the survival of patients with advanced lung cancers. Limitations to this quest remain misdiagnosis and delayed diagnosis and resource constraints for both molecular testing and subsequent treatments.

Prostate Cancer Screening, Diagnostic, Treatment Procedures and Costs in Sub-Saharan Africa: A Situational Analysis.

PURPOSE: Prostate cancer mortality is predicted to nearly double by 2040 in Sub-Saharan Africa (SSA). The lack of prostate cancer screening in SSA contributes to late-stage diagnosis, treatment delays, and poor survival among patients. We analyzed the availability and use of prostate cancer screening, diagnostic and treatment guidelines, procedures, and costs in few SSA countries to determine factors for consideration in the development of prostate cancer screening guidelines for SSA. METHODS: We applied mixed methods approaches to collect data through an electronic survey administered to clinicians (oncologists, urologists, pathologists, nurses, and radiation oncologists) providing prostate cancer screening, diagnosis, and treatment services in multiple sub-Saharan countries. RESULTS: Inconsistencies in respondents' understanding of the availability and use of prostate cancer screening guidelines in their countries were noted. Prostate Specific Antigen (PSA) and Digital Rectal Examination (DRE) were the most commonly available screening modalities. Available diagnostic procedures included a combination of prostate biopsies, transrectal ultrasonography, and DRE. Our study's data suggest that PSA and DRE exams are available for early diagnosis and screening procedures. Availability of treatment modalities with curative intent and costs for prostate cancer related procedures varied between and within countries. CONCLUSIONS: PSA and DRE are available for detecting prostate cancer and may detect aggressive cancers early, leading to improved outcomes. However, PSA screening is also associated with overdiagnosis and over-treatment. National prostate cancer policies should consider health systems, evidence-based guidelines, population characteristics and healthcare financing to ensure access to clinically relevant and safe prostate cancer related care.

Feasibility Study of a Smartphone Application for Detecting Skin Cancers in People With Albinism.

PURPOSE: Albinism affects some facets of the eye's function and coloration, as well as hair and skin color. The prevalence of albinism is estimated to be one in 2,000-5,000 people in sub-Saharan Africa and one in 270 in Tanzania. People in Tanzania with albinism experience sociocultural and economic disparities. Because of stigma related to albinism, they present to hospitals with advanced disease, including skin cancers. Mobile health (mHealth) can help to bridge some of the gaps in detection and treatment of skin cancers affecting this population. METHODS: We assessed the feasibility of using a mobile application (app) for detection of skin cancers among people with albinism. The study was approved by the Ocean Road Cancer Institute institutional review board. Data, including pictures of the lesions, were collected using a mobile smartphone and submitted to expert reviewers. Expert reviewers' diagnosis options were benign, malignant, or unevaluable. RESULTS: A total of 77 lesions from different body locations of 69 participants were captured by the NgoziYangu mobile app. Sixty-two lesions (81%) were considered malignant via the app and referred for biopsy and histologic diagnosis. Of those referred, 55 lesions (89%) were biopsied, and 47 lesions (85%) were confirmed as skin malignancies, whereas eight (15%) were benign. CONCLUSION: With an increasing Internet coverage in Africa, there is potential for smartphone apps to improve health care delivery channels. It is important that mobile apps like NgoziYangu be explored to reduce diagnostic delay and improve the accuracy of detection of skin cancer, especially in stigmatized groups.

Burundi Cancer Care Needs: A Call to Action.

Burundi is a landlocked country in the East Central Africa region. Beyond a long civil war strife, cancer care remains overlooked, in terms of both infrastructure and human resources needs, and it shows from estimated global incidence and mortality figures. Through a focused literature search, this study highlights the main cancer care needs in this country, with the aim to gather global oncology support to Burundi. IMPLICATIONS FOR PRACTICE: There is little knowledge about the state of oncology in Burundi. This article, based on a literature search, depicts an image of the current state of cancer care in Burundi and aims to compel global health enthusiasts to join in curbing the death toll of cancers in Burundi.

Choosing Wisely Africa: Ten Low-Value or Harmful Practices That Should Be Avoided in Cancer Care.

PURPOSE: Choosing Wisely Africa (CWA) builds on Choosing Wisely (CW) in the United States, Canada, and India and aims to identify low-value, unnecessary, or harmful cancer practices that are frequently used on the African continent. The aim of this work was to use physicians and patient advocates to identify a short list of low-value practices that are frequently used in African low- and middle-income countries. METHODS: The CWA Task Force was convened by the African Organization for Research and Training in Cancer and included representatives from surgical, medical, and radiation oncology, the private and public sectors, and patient advocacy groups. Consensus was built through a modified Delphi process, shortening a long list of practices to a short list, and then to a final list. A voting threshold of ≥ 60% was used to include an individual practice on the short list. A consensus was reached after a series of teleconferences and voting processes. RESULTS: Of the 10 practices on the final list, one is a new suggestion and 9 are revisions or adaptations of practices from previous CW campaign lists. One item relates to palliative care, 8 concern treatment, and one relates to surveillance. CONCLUSION: The CWA initiative has identified 10 low-value, common interventions in Africa's cancer practice. The success of this campaign will be measured by how the recommendations are implemented across sub-Saharan Africa and whether this improves the delivery of high-quality cancer care.

State of Cancer Control in Rwanda: Past, Present, and Future Opportunities.

Rwanda is a densely populated low-income country in East Africa. Previously considered a failed state after the genocide against the Tutsi in 1994, Rwanda has seen remarkable growth over the past 2 decades. Health care in Rwanda is predominantly delivered through public hospitals and is emerging in the private sector. More than 80% of patients are covered by community-based health insurance (Mutuelle de Santé). The cancer unit at the Rwanda Biomedical Center (a branch of the Ministry of Health) is responsible for setting and implementing cancer care policy. Rwanda has made progress with human papillomavirus (HPV) and hepatitis B vaccination. Recently, the cancer unit at the Rwanda Biomedical Center launched the country's 5-year National Cancer Control Plan. Over the past decade, patients with cancer have been able to receive chemotherapy at Butaro Cancer Center, and recently, the Rwanda Cancer Center was launched with 2 linear accelerator radiotherapy machines, which greatly reduced the number of referrals for treatment abroad. Palliative care services are increasing in Rwanda. A cancer registry has now been strengthened, and more clinicians are becoming active in cancer research. Despite these advances, there is still substantial work to be done and there are many outstanding challenges, including the need to build capacity in cancer awareness among the general population (and shift toward earlier diagnosis), cancer care workforce (more in-country training programs are needed), and research.

Attitudes and Barriers to Research Among Oncology Trainees in East Africa.

BACKGROUND: East Africa is one of the fastest growing regions in the world and faces a rising burden of cancer; however, few people are equipped to effectively conduct research in this area. MATERIALS AND METHODS: A 31-item questionnaire was distributed to current trainees and recent graduates of the Master in Medicine in Clinical Oncology Program at Muhimbili University of Health and Allied Sciences in Tanzania. Areas that were assessed included (a) demographic information, (b) prior research training, (c) prior and current research activities, (d) attitudes toward the importance of research, and (e) supports and barriers to inclusion of research in an oncology career path. RESULTS: A total of 30 individuals responded to the survey, of whom 53% (n = 16) were male and 70% (n = 21) identified as current trainees. Among the majority of respondents, attitudes toward research were strongly favorable. Although only 37% (n = 11) reported receiving any formal training in research methodology, 87% (n = 26) reported intentions to incorporate research into their careers. The absence of protected time for research and lack of access to research funding opportunities were identified by a majority of respondents as critical barriers. CONCLUSION: A majority of current or recent oncology trainees in Tanzania desire to incorporate research into their careers, but most also lack adequate training in research methodology and longitudinal mentorship. Our future collaboration will focus on creation of appropriate research training curriculums and fostering an environment that catalyzes interprofessional development and transforms and extends context-specific cancer research in East Africa. IMPLICATIONS FOR PRACTICE: Current and recent oncology trainees in East Africa expressed a high enthusiasm for research, driven by a sense of urgency related to the burden from cancer that the region faces. This highlights the need for cancer research training and mentorship in this setting. This work hypothesizes that African principal investigators can operate effectively if proper attention is given to selection and provision of high-quality foundational didactic training to learn the theory and implementation of research as well as to the development of an environment conducive to mentoring.

Is HINARI appropriate for medical students in the developing world?

The Health InterNetwork Access to Research Initiative (HINARI), which arose in response to medical literature needs in developing countries, gives online access to scientific information to a variety of institutions throughout the world. This is a great resource; however, little research has been performed on the effectiveness and usefulness of HINARI, specifically to medical schools. Our study sought to find out whether the textbooks (e-books) available on HINARI could form a virtual library that would cover the curriculum of a medical school. After categorising and reviewing the medically relevant e-books on HINARI, we found that they were insufficient in providing adequate subject material relevant to medical school curricula from Rwanda, the United Kingdom and the United States. This literature gap could be closed by additional medical textbooks being made available from contributing publishers. An increase of only 14% in HINARI e-book resources would provide material for the entire medical school curriculum.
